Hi,

I have a asp.net page in which I am want to pass parameters to a rad window. I want to access that parameter in the rad window page_load method on the server side. I am not able to able to access this value as it is at the very initial stages to load. But, I can access the parameter at client level by writing onload method on body tag like this:

<script language="javascript" type="text/javascript">
function GetRadWindow()
{
var oWindow = null;
if (window.radWindow)
     oWindow = window.radWindow;
else if (window.frameElement.radWindow)
     oWindow = window.frameElement.radWindow;
return oWindow;
}

function receiveArg()
{
   var currentWindow = GetRadWindow();
   alert(currentWindow.argument);

}
</script>

</head>
<body onload="receiveArg();">
<form id="form" runat="server">

But, I dont want to do this at the client level. I require this value in page load at server side as I need to do some business logic over it.

Is there any way to get this????

Thanks,
Mahesh

Hi Mahesh,

You are transferring the argument to the content page on the client only (with JavaScript). That is why you cannot access it on the server - you need to "send it there" somehow. This could happen either by submitting the form / postback or by using Ajax call.
Sending arguments from the client to the server is not related to the RadWindow control but is a general programming task. There are various ways to do that (__doPostBack() / ajax call), but since you are using RadControls and I assume you want to avoid postbacks, I suggest to use the RadAjaxManager's client-side API and ajaxRequest().

As an alternative you could send arguments from the parent page to the content one via the query string like shown in the following demo:
